Hi Tavian - a number of years ago, a friend and colleague actually introduced Financial Literacy ( a course) into high school. Unfortunately it didn't take off, but now, here in Australia, the need is being highlighted, starting in primary years.
Here is a little article I wrote about how freinds of mine, started their children on their journey of financial knowledge. I believe the sooner we start the better we aill handle money. https://medium.com/change-your-mind/dear-parents-about-your-childs-finances-4e4f01cff794
